Abstract
The utility model provides a 45-DEG air chamber support, which comprises a support seat and a support holder. The support seat is provided with a bottom hole and is connected with the support holder through a support wall. The part of the support wall connected with the support seat is provided with a camshaft hole protruding out of the support wall. One side of the support wall is provided with an outwardly convex support rib along the camshaft hole. The 45-DEG air chamber support is characterized in that the outwardly convex support rib is a linear straight rib. Due to the adoption of the above design, the technique of machining the bottom hole of the support seat is improved, while the number of planes to be machined during the machining of the support wall is also reduced. The additional surplus material is simultaneously removed.
Description
Technical field
The utility model relates to a kind of air chamber support, relates to 45 ° of air chamber supports that a kind of 457 drive axles use specifically, belongs to automobile technical field.
Background technology
Continuous development along with the highway in China construction; Road transport develops to the direction of lightweight, high reliability with commercial vehicle/comm..vehicle; In order to comply with this development tendency, domestic each tame commercial vehicle/comm..vehicle producer all carries out the transformation of lightweight and high reliability at the parts to oneself.
The support muscle of 45 ° of air chamber supports of 457 bridges of the prior art is the rectilinear curved muscle of right and wrong all, when being the carrier base machined bottom, because the interference of curved muscle can have influence on the processing technology to bottom outlet.Simultaneously because in support holder one side, the surface of the hole face protruding bracket wall of camshaft hole, the processing plane during increase processing cradle wall that can be extra has not only reduced work efficiency, has also increased extra material more than needed, has strengthened the weight of 45 ° of air chamber supports.
Along with the increase of car load coupling engine horsepower, the raising of the lifting of 457 drive axle load-carrying capacitys and the specified air pressure of car load, existing 45 ° of air chamber supports have satisfied not the requirement of extensive air chamber power output.
The utility model content
The utility model technical matters to be solved; Overcome the deficiency of above-mentioned prior art exactly; A kind of processing technology that both can improve the carrier base bottom outlet is provided, can reduces the processing plane when processing cradle wall again, removed 45 ° of air chamber supports of extra material more than needed simultaneously.
In order to solve above-mentioned technical matters, the utility model adopts following technical scheme:
A kind of 45 ° of air chamber supports; Comprise the carrier base and the support holder that have bottom outlet; Carrier base and support holder link together through cradle wall; The part that on cradle wall, links to each other with carrier base has the camshaft hole of protruding bracket wall, and along a side of camshaft hole the support muscle of evagination is arranged at cradle wall, and described support muscle is the straight muscle of linear.
Further, in support holder one side, the hole face of camshaft hole is on the surface of cradle wall.
The beneficial effect of the utility model is:
Because change the support muscle into straight muscle, can avoid for the carrier base machined bottom time, having influence on the processing technology of bottom outlet.
Because in support holder one side, the hole face of camshaft hole is on the surface of cradle wall, and promptly extra material more than needed has not only been removed on the camshaft hole surface of protruding bracket wall not, the processing plane when also having reduced the processing cradle wall.

Fig. 2 is the birds-eye view of the utility model embodiment 1.
Fig. 3 is the left view of the utility model embodiment 1.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, below in conjunction with accompanying drawing and embodiment, to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment 1, please with reference to Fig. 1, Fig. 2 and Fig. 3, the utility model discloses a kind of 45 ° of air chamber supports that are applied on speciality car 457 drive axles; This support comprises the carrier base 1 and support holder 2 that has circular bottom outlet; Carrier base 1 links together through cradle wall 3 with support holder 2, in the present embodiment, and under the prerequisite of avoiding interfering; Can increase the thickness of cradle wall 3; The part that on cradle wall 3, links to each other with carrier base 1 has cylindric camshaft hole 4, and this camshaft hole 4 is outside carrier base 1 one side protruding bracket walls 3, and this camshaft hole 4 is on its hole face of support holder 2 one sides surface of protruding bracket wall 3 not; Along a side of camshaft hole 4 the linear support muscle 5 of evagination is arranged at cradle wall 3, promptly straight muscle.Such structure design both can improve the processing technology to the carrier base bottom outlet; Processing plane in the time of can reducing the processing cradle wall again; Removed extra material more than needed simultaneously; The requirement of air chamber power output has improved support single-piece stress and displacement performance when under the prerequisite that does not improve the air chamber weight support frame, satisfying the specified air pressure of car load (1Mpa).
Claims (2)
1. 45 ° of air chamber supports; Comprise the carrier base and the support holder that have bottom outlet; Carrier base and support holder link together through cradle wall; The part that on cradle wall, links to each other with carrier base has the camshaft hole of protruding bracket wall, and along a side of camshaft hole the support muscle of evagination is arranged at cradle wall, and it is characterized in that: described support muscle is the straight muscle of linear.
2. 45 ° of air chamber supports according to claim 1 is characterized in that: in support holder one side, the hole face of camshaft hole is on the surface of cradle wall.
