Abstract
The invention discloses a novel suspension device for a back stay of a gear box, which comprises a large bush and a small bush connected through a support, and the large bush comprises an external tube connected through vulcanization and a core and is characterized in that arc grooves are arranged at the front end and the rear end of the core, rubber is distributed in the groove at the rear end so as to form a convex part, the rubber is distributed along the arc of the groove at the front end so as to form a first convex part, a second convex part and a third convex part, the first convex part and the second convex part are arranged at the tips of two ends of the groove at the front end, the second convex part is arranged at the middle part of the groove at the front end, a main collision block is vulcanized at the position of the second convex part right corresponding to the internal wall of the external tube, a first collision block and a second collision block are symmetrically arranged at two sides of the main collision block, the first collision block corresponds to the position of the first convex part, and the second collision block corresponds to the position of the third convex part. The novel suspension device has the advantages that the suspension device is light, has low cost and good buffer performance, effectively lightens internal vibration and lowers the noise.
Description
Technical field
The present invention relates to a kind of suspension, particularly relate to a kind of change speed gear box back pull rod suspension.
Background technology
Change speed gear box back pull rod suspension is a kind of structure that power assembly suspension system is comparatively conventional, and Main Function controls dynamic assembly moving displacement and windup-degree, reduces vibration and the noise of car body.
Existing change speed gear box back pull rod suspension is generally made up of Large lining, little lining and support, Large lining and the direct interference fit of support, the outer sulfuration iron ring of little lining, by iron ring and support interference fit, Operating Weight like this is large, cost is high, and during specific works, Large lining rotates and easily causes the inefficacy of part.Generally arrange a main collision block in Large lining in addition, when automobile is in acceleration and moderating process, there is a collision process in the rubber spring in lining and main collision block, cushion characteristic is relatively poor, thus make to occur the problems such as shake and noise in car.
Summary of the invention
Technical matters to be solved by this invention is to provide the good change speed gear box back pull rod suspension of a kind of cushion characteristic.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of change speed gear box back pull rod suspension, comprise Large lining and little lining, described Large lining is connected by support with little lining, described Large lining comprises outer tube and inner core, described inner core is connected by the vulcanization of rubber with outer tube, the front-end and back-end of described inner core are provided with the inner groovy of circular arc, described rubber is distributed in the lug boss that in the inner groovy of rear end, formation one is corresponding with inner groovy, described rubber is along arc distribution formation first lug boss of front end inner groovy, second lug boss and the 3rd lug boss, the first described lug boss and the 3rd lug boss are arranged on the wedge angle position at inner groovy two ends, front end, the second described lug boss is arranged on the middle part of front end inner groovy, just a main collision block is had to sulfuration on the inwall of described outer tube at the second lug boss, the first collision block and the second collision block is symmetrically arranged with on the both sides of main collision block, the first described collision block is corresponding with the position of the first lug boss, the second described collision block is corresponding with the position of the 3rd lug boss.
Straight-line distance between the second described lug boss and main collision block is 2-4mm.
Described support comprises Large lining installing ring and little lining installing ring, described Large lining installing ring inwall is provided with uniform boss, described Large lining by described boss and Large lining installing ring interference fit, described little lining and the described direct interference fit of little lining installing ring.
Compared with prior art, the invention has the advantages that:
(1) multiple lug boss is set in Large lining inside with collision block, when automobile is in acceleration and moderating process, in lining there is multiple collision process in each rubber bumps portion and collision block, and cushion characteristic is relatively better, thus the problem such as the shake solved preferably in car and noise.
(2) the direct interference fit of little lining installing ring on little lining and support, decreases sub-number of components, alleviate the total mass of suspension, reduce costs, and effect is better.
(3) by the inner convex platform of Large lining installing ring on support and Large lining outer tube elastic conjunction, while ensureing extrusion pressure, effectively prevent Large lining and rotate and the part failure that causes.
