Description
Technical field
The utility model relates to vehicular spare parts field, is specifically related to a kind of brake assembly being applicable to 3 ~ 10 tonnage car front steering drive axles.
Background technology
Along with the progress of society, the productive life level of people day by day improves.We are more and more various to the demand of automobile, and this also creates the varied of automobile.The automobile of little tonnage rank, such as light truck, low-speed truck etc., the wheel rim adopted due to this type automobile is less, so limit the volume of the brake assembly of such automobile.Generally employ oily brake in early days, due to the poor stop that oil is stopped, cannot meet the demand of people.The mode such as reducing the volume of the ironcasting of automobile front axle then adopted, to install compressed air brake cylinder, although reach the requirement of deceleration and stopping performance, is reduction of the intensity of automobile front axle, causes that cosmetic vehicle is fragile, the adverse consequences such as be not durable.And the drg that on market, existing camshaft is obliquely installed, excessive due to angle of inclination, machinery driving efficiency is too low, thus have impact on braking effect.
Summary of the invention
The problems such as the utility model provides a kind of brake assembly of car front steering drive axle, and the braking effect in order to the car brake solving existing little tonnage rank is poor, be not durable.
The utility model adopts following technical scheme:
A brake assembly for car front steering drive axle, comprises brake drum assembly, compressed air brake cylinder, camshaft, adjustment arm and support.Above-mentioned support the inner is fixedly assemblied in the outer face of above-mentioned brake drum assembly, offers cylindrical hole in the middle of support the inner, and the line of centers of this through hole is 3 ° to 7 ° with the angle perpendicular to the vertical line of brake drum assembly outer face, and is preferably 4 ° to 6 °.Above-mentioned compressed air brake cylinder is fixedly assemblied in support outer end.Above-mentioned camshaft the inner is extended in brake drum assembly by the through hole of support the inner.The inner fixed cover of above-mentioned adjustment arm is located at camshaft outer end, adjustment arm outer end and compressed air brake cylinder hinged.The selection of this angle of this through hole, makes the adjustment arm of camshaft outer end can avoid interfering with the steering swivel shell being assemblied in brake drum assembly, avoids the brake wheel of the inner of camshaft and brake drum assembly to interfere simultaneously.
Further:
Above-mentioned support the inner is fixedly assemblied in brake drum assembly madial wall by two bolts.
The inner place plane of above-mentioned support and plane included angle, place, outer end are 83 ° to 87 °.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
The first, the utility model compact conformation, volume are little, can use compressed air brake cylinder in the wheel rim that size is less, to reach better braking effect.The second, camshaft angle of inclination of the present utility model is less, advantageously in mechanical drive, brake efficiency is higher, braking effect is better.3rd, the utility model is under the prerequisite obtaining better braking effect, and the propons for automobile leaves enough large space, ensure that the intensity of the automobile front axle under same material.

Fig. 1 is the structural representation of brake assembly of the present utility model.
Fig. 2 is the structural representation of support of the present utility model.
Fig. 3 is the plan structure schematic diagram of support of the present utility model.
Fig. 4 is the sectional structure schematic diagram of support of the present utility model along A-A direction in Fig. 3.
Detailed description of the invention
Detailed description of the invention of the present utility model is described with reference to the accompanying drawings.
Referring to figs. 1 to 4, a kind of brake assembly of car front steering drive axle, comprises brake drum assembly 1, compressed air brake cylinder, camshaft 2, adjustment arm 3 and support 4.Above-mentioned support the inner 41 is fixedly assemblied in the outer face of above-mentioned brake drum assembly 1 by two bolts, offers cylindrical hole 411 in the middle of support inner 41, and the line of centers of this through hole 411 is 5 ° with the angle perpendicular to the vertical line of brake drum assembly 1 outer face.Above-mentioned compressed air brake cylinder is fixedly assemblied in support outer end 42.The inner 41 place planes of above-mentioned support and plane included angle, place, outer end 42 are 85 °.Above-mentioned camshaft 2 the inner is extended in brake drum assembly 1 by the through hole 411 of support the inner 41.Inner 31 fixed covers of above-mentioned adjustment arm are located at camshaft 2 outer end, and adjustment arm outer end 32 is hinged with compressed air brake cylinder.In drg use procedure of the present utility model, compressed air brake cylinder drives adjustment arm 3, thus camshaft 2 is rotated, thus struts the brake facing in brake drum assembly 1, in order to reach the effect of braking.The selection of this angle of this through hole 411, had both contributed to the volume reducing brake assembly, and had made brake assembly of the present utility model can be applied in less wheel rim; Also make the adjustment arm 3 of camshaft 2 outer end can avoid interfering with the steering swivel shell 11 being assemblied in brake drum assembly 1, avoid the brake wheel 12 of the inner of camshaft 2 and brake drum assembly 1 to interfere simultaneously.And the angle of inclination that camshaft 2 is less, the machinery driving efficiency of camshaft 2 can be increased, be conducive to the brake efficiency of Hoist braking device, ensure braking effect.
Above are only detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
