Abstract
The utility model relates to a wheel hub of rear wheel drive vehicle and drum brake's subassembly. The brake device comprises a drum brake, a buffer block mounting plate, an L-shaped lower mounting bracket arm and a hub bearing unit. The hub bearing unit is connected with one L-shaped side wall of the lower mounting bracket arm through a mounting through hole of the brake bottom plate by using a connecting bolt; at the top end of the side wall, the buffer block mounting plate is connected with the lower mounting bracket through a bolt. The utility model discloses not only provide a rear wheel drive vehicle's wheel hub and drum brake's subassembly, still provide one kind with the form of being connected of the non-independent suspension structure in back. The structure is simple and compact, the occupied space is small, and the cost of the whole vehicle is greatly reduced.
Description
Technical field
The utility model relates to automobile technical field, particularly relates to the wheel hub of a kind of rear wheel drive electric vehicle application and the assembly of drum brake.
Background technique
In automotive engineering, light-duty or microbus adopts engine behind front wheel or form that is mid-and rear wheel drive usually.Under this drive form, the back driving axle assembly structure that rear axle adopts ransaxle and left and right drum brake to form usually.Under this structure, rear axle assy need be connected with power assembly with by transmission shaft.This kind of structural type is in electric vehicle development process, due to the existence of transmission shaft, the battery causing being arranged under vehicle body lower floor effectively cannot utilize space, often needs battery to be divided into two cell bag in left and right for dodging transmission shaft simultaneously, brings adverse effect to the performance of battery and life-span.
In electric vehicle development process, the power assembly that the power assembly overall dimension opposite engine gearbox be made up of motor and deceleration forms greatly reduces.In this case, be fully reserved battery arrangement space, can by motor arrangement at rear axle position, the Power output line of retarder in the vehicle width direction, by the axial wheel transferring power in left and right half.Form rear axle assy by back driving axle and drum brake in this case and cannot meet usage requirement, therefore need a kind of brand-new structure of exploitation to meet the demand of this type of vehicle.
Model utility content
In order to overcome the above problems, the utility model provides a kind of wheel hub of rear wheel drive vehicle and the assembly of drum brake, meets the demand of this type of vehicle.
The purpose of this utility model is achieved through the following technical solutions:
The wheel hub of rear wheel drive vehicle and an assembly for drum brake, comprise drum brake, also comprises buffer stopper mounting plate, the lower installation trailing arm of L shape and hub-bearing unit; Hub-bearing unit application connecting bolt is connected with a sidewall of the L shape of lower installation trailing arm by the installation via hole of brake backing plate; On this sidewall top, buffer stopper mounting plate is linked together by bolt and lower installation trailing arm.
Described connecting bolt and installation via hole are four.
The utility model not only provides a kind of wheel hub of rear wheel drive vehicle and the assembly of drum brake, also in the Connecting format providing a kind of and rear rigid axle suspension structure.The utility model structure is simple, compact, takes up room little, while overcoming the above problems, greatly reduces integral vehicle cost.

Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 shows the schematic diagram of brake inside structure for embodiment described in Fig. 1.
Fig. 3 is the schematic diagram that the utility model is connected with automobile associated components.
In accompanying drawing:
1-break, 2-buffer stopper mounting plate, installs trailing arm under 3-, 4-hub-bearing unit.
Embodiment
For enabling above-mentioned purpose, feature and advantage become apparent more, when considered in conjunction with the accompanying drawings, by referring to detailed description below, more completely can understand the utility model better, and easily learn its adjoint advantage.Accompanying drawing described herein is used to provide further understanding of the present utility model, form a part for the utility model patent, the schematic description and description of the utility model patent, for explaining the utility model, does not form the improper restriction to the utility model patent.
Below in conjunction with the specific embodiment shown in Fig. 1 to Fig. 3 and Tu, the utility model is described in further detail:
The wheel hub of rear wheel drive vehicle and an assembly for drum brake, comprise drum brake 1, buffer stopper mounting plate 2, the lower installation trailing arm 3 of L shape and hub-bearing unit 4.Hub-bearing unit 4 is applied four connecting bolts and is connected with a sidewall of the L shape of lower installation trailing arm 3 by four installation via holes of break 1 base plate; On this sidewall top, buffer stopper mounting plate 2 is linked together by bolt and lower installation trailing arm 3.
Described the utility model assembly to be connected with transmission shaft (not shown) by the spline structure of hub-bearing unit 4, is connected (see Fig. 3) with leaf spring and vibration damper by lower installation trailing arm 3; Be connected with transmission shaft, wheel set by hub-bearing unit 4 simultaneously.
The utility model assembly, by being connected with jack shaft, rear leaf spring, vibration damper and wheel set, realizes the driving to vehicle.
In vehicle structure, usual drum brake coordinates practicality with rear axle structure usually, but above-mentioned conventional construction can not semi-axis structure with the use of.Therefore, in electric vehicle development process, exploitation one can with jackshaft with the use of, realize the wheel hub that drives and the assembly of drum brake very necessary.This assembly is by being connected with leaf spring, transmission shaft, tire assembly the driving realized vehicle.
As mentioned above, the embodiment of the utility model patent is explained, but as long as do not depart from fact the model utility point of the utility model patent and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation is also all included within the protection domain of the utility model patent.
