前言
本标准第4章、第5章、第6章为强制性的,其余为推荐性的。
本标准修改采用78/549/EEC《成员国关于汽车护轮板的法规》(94/78/EC修订版)。
本标准根据78/549/EEC重新起草,在附录A中列出本标准章条编号与78/549/EEC法规章条编
号的对照一览表。
考虑到我国国情,在采用78/549/EEC法规时,本标准做了一些修改,本标准与78/549/EEC主要
技术性差异及其原因如下:
---删除78/549/EEC中认证申请(附录Ⅰ第4章)、认证批准(附录Ⅰ第5章)、认证修改(附录Ⅰ
第6章)、产品一致性(附录Ⅰ第7章)、资料文件(附录Ⅱ)、认证标识(附录Ⅲ)等内容,其原因
是标准体系与法规体系的形式差异所致;
---“当车辆在运转状态,前排坐一名乘员(78/549/EEC附录Ⅰ中2.1)”改为“当车辆在整备质量
状态,前排坐2名65kg的乘员(本标准中5.1)”。其原因是考虑到我国人体体重的因素,乘员
质量按平均计算质量65kg计算。
为便于使用,本标准还做了下列编辑性修改:
---“本法规”改为“本标准”;
---增加资料性附录A。
本标准代替GB 7063-1994《汽车护轮板》。
本标准与GB 7063-1994的差异:
---本标准在本版“5.1”修改了测量时的试验条件;
---本标准在本版“6”增加了防滑链的使用要求。
本标准的实施过渡期:对于新产品,自标准实施之日起实施;对于新生产车(已上公告车),自标准实
施之日起24个月后实施。
本标准由国家发展和改革委员会提出。
本标准由全国汽车标准化技术委员会归口。

Foreword
Article 4, 5, 6 of this Standard are compulsory and the others are voluntary.
This Standard was drafted by modifying and adopting 78/549/EEC, The Laws of the
Member States Relating to the wheel Guards of Motor Vehicles (Revision 94/78/EC).
This Standard was redrafted in accordance with 78/549/EEC. The list of comparison
between the article numbers in this Standard and those in 78/549/EEC is given in
Annex A.
Considering the national conditions of China, some modifications are made in this
Standard when Directive 78/549/EEC is adopted. The major technical differences
between this Standard and 78/549/EEC and their reasons are as follows.
-- the content including application for approval (Article 4 of Annex I), granting of
approval (Article 5 of Annex I), modification of approval (Article 6 of Annex I),
product uniformity (Article 7 of Annex I), informative documents (Annex II) and
approval mark is deleted, and the reason is the differences in the forms of the
standard system and legal systems;
-- “when the vehicle is in running order with one passenger in the front row (2.1 in
Annex I of 78/549/EEC)” is changed into “when the vehicle is in running order with
two passengers in the front row (5.1 of this Standard)”. The reason is that
considering the factors relating to the body weight of Chinese, the weight of
passengers is calculated in accordance with the average calculated weight 65 kg.
For the convenience of use, the following modifications are made in this Standard.
-- “this Directive” is changed into “this Standard”;
-- informative Annex A is added.
This Standard replaces GB 7063-1994, The Wheel Guards of Motor Vehicles.
The differences between this Standard and GB 7063-1994.
-- the test conditions of measurement are modified in “5.1” of this Standard;
-- the requirements for use of chains are added in “6” of this Standard.
The transitional period for the implementation of this Standard. for new products, it
shall be implemented from the date of implementation of this Standard; for newly-
produced vehicles (those indicated in the Announcement), it shall be implemented 24
months after the implementation of this Standard.
This Standard was proposed by the National Development and Reform Commission.
The Wheel Guards of Motor Vehicles
1 Application Scope
This Standard specifies the specifications for the wheel guards of motor vehicles.
This Standard applies to the motor vehicles of category M1.
2 Normative References
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For dated references, the subsequent amendments
(excluding corrigendum) or revisions do not apply to this Standard, however, parties
who reach an agreement based on this Standard are encouraged to study if the latest
of the referenced document applies.
GB/T 15089-2001, Classification of Power-driven Vehicles and Trailers
3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
wheel guards
The parts which are located above the wheels and function to block the thrown-up mud,
stones and others generated during the operation of the wheels. They may be
independent parts, as well as parts of the bodywork.
4.1 The motor vehicles must be provided with wheel guards (parts of the bodywork,
mud-guards, etc.)
4.2 The wheel guards must be so designed as to protect other road users, as far as
possible, against thrown-up stones, mud, ice, snow and water and to reduce for those
users the dangers due to contact with the moving wheels.
5 Special Requirements
5.1 The wheel guards must meet the following requirements when the vehicle is in
running order with two passengers1 in the front row and the wheels are in the dead
ahead position.
rear of the centre of the wheels (see Figure 1), the overall width (q) of the wheel guards
must be at least sufficient to cover the total tyre width (b) taking into account the
extremes of the tyre/wheel combination as specified by the manufacturer. In the case
of twin wheels, the total width over the two tyres (t) shall be taken into account.
The width of the wheels. the labelling (marking) and decorations, protective bands or
ribs on tyre walls are not taken into account.
5.1.2 The rear of the wheel guards must not terminate above a horizontal plane 150
mm above the axis of rotation of the wheels and furthermore the intersection of the
edge of the wheel guard with its plane (point A, Figure 1) must lie outside the median
plane of the outmost tyre.
5.1.3 The contour and location of the wheel guards shall be such that they are as
close to the tyre as possible; and in particular within the part formed by the radial planes
referred to in 5.1.1, they shall satisfy the following requirements.
5.1.3.1 the projection – situated in the vertical plane of the tyre axis – of the depth (p)
of the outer edge of the wheel guards, measured in the vertical longitudinal plane
passing through the centre of the tyre, must be at least 30 mm. This depth (p) may be
reduced progressively to zero at the radial planes specified in 5.1.1;
5.1.3.2 the distance (c) between the lower edges of the wheel guards and the axis
of the tyre.
5.1.4 In the case of vehicles having adjustable suspension height, the above-
mentioned requirements must be met when the vehicle is in the normal running
position specified by the vehicle manufacturer.
5.2 The wheel guards may consist of several components, provided no gaps exist
between or within the individual parts when assembled.
5.3 The wheel guards must be firmly attached. However, they may be detachable
either as a unit or in parts.
1 The mass of passengers is calculated as 65 kg.
