Technical field
The utility model relates to a kind of novel air chamber bracket assembly device.
Background technology
Automobile-used air chamber support is the device that is used to support compressed air brake cylinder, and there are a lot of defectives in present automobile-used air chamber holder device, and structure design is unreasonable; Support strength is not high, and stress is too concentrated, and the short time uses phenomenon of rupture often takes place; Influenced result of use; Particularly the air chamber rocking arm is greater than 200mm, and lock torque increases, and the air chamber support ruptures more easily.
Summary of the invention
The utility model provides a kind of novel air chamber bracket assembly device to the above-mentioned deficiency that existing automobile-used air chamber support exists.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of novel air chamber bracket assembly device comprises the air chamber support; Compressed air brake cylinder links to each other with said air chamber support; Be welded on the stay bearing plate on the said air chamber support; Connect back-plate on the said stay bearing plate, mounting cam axle in said air chamber support and the camshaft sleeve inblock cast, said camshaft sleeve.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, in the said camshaft sleeve lining is installed, said air chamber support connects through lining and camshaft.
Further, the inner peripheral surface of lining is provided with 3 plug helixs on the said camshaft sleeve.
Further, said stay bearing plate is connected on the camshaft sleeve through the mode of welding.
Further, have through hole on the said stay bearing plate, be inserted with bolt in the said through hole, said stay bearing plate passes through bolted connection on back-plate.
Further, the outside face of the attachment face of said air chamber support and compressed air brake cylinder and camshaft sleeve is tangent.
Further, the attachment face of said air chamber support and compressed air brake cylinder is provided with L shaped reinforced rib, and the outside face of said L shaped reinforced rib and camshaft sleeve is tangent.
Further, have Baltimore groove on the attachment face of said air chamber support and compressed air brake cylinder, the both sides of said Baltimore groove have reinforced rib.
The beneficial effect of the utility model is: the utility model is an automobile-used novel air chamber bracket assembly device under a kind of longer air chamber rocking arm situation, and the air chamber support is set up reinforced rib, reaches the effect that stress disperses; Transition position is difficult for jackknifing, and prolong service life, and can reduce the deformation quantity under the air chamber support force state; Thicker part digs out the matrix face; Prevent shrinkage porosite with loose, but improved castability, increased intensity; Camshaft sleeve mounting bush inner peripheral surface is provided with 3 plug helixs; This structure setting is storing lubricating oil as much as possible; Do not need in the camshaft upper shed; Increase the intensity of camshaft effectively, under lock torque increase situation under the long rocking arm situation, eliminated the potential safety hazard of air chamber bracket assembly.
