Description
Technical Field
The utility model belongs to the technical field of suspension support behind the engine and specifically relates to a suspension support behind multi-functional engine.
Background
When the series of engine models such as Yuchai YC4E/YC4D/YC4S are matched for development at the present stage, the distance between the engine rear suspension and the starter on the engine on the right side is very small due to the structure limitation of the engine body, and when the engine rear suspension support is designed, the engine rear suspension support is often subjected to notch cutting treatment in order to avoid the interference between the starter and the engine rear suspension support. Because the notch is irregular in shape, the notch cutting treatment is difficult to control and inspect in the actual production process, the problem that the gap between the rear suspension bracket of the engine and the starter is small often occurs after loading, interference is generated during bumping, and the starter is easy to collide and damage in severe cases.
In order to avoid the problems, when the engine rear suspension support is designed in a whole vehicle factory, the engine rear suspension support is designed to be in an eccentric structure, namely, the connection position of an upper engine body of the engine rear suspension support is not aligned with the connection position of an engine cushion, and a certain deviation exists in the front-rear direction, so that the gap between the engine rear suspension support and a starter is increased, and the starter is prevented from interfering with the engine rear suspension.
Because of there is the gearbox behind the engine, arrange the engine above the gearbox and select the flexible axle support of shifting, select to shift the manipulation flexible axle of shifting right side and upside arrangement of flexible axle support, the engine rear suspension after-shift has taken up the space of arranging of flexible axle and flexible axle support, will cause the engine rear suspension support and select the flexible axle support of shifting, select the flexible axle of shifting and the engine rear suspension support problem of producing the interference because of the clearance is little, although this interference can not cause the reduction of engine and gearbox performance, but can cause the engine rear suspension in actual production process and use, it is inconvenient to select the flexible axle of shifting to dismantle the change, reduce assembly production efficiency, bring great complaint.
On one hand, the engine suspension support and the gear selecting and shifting flexible shaft support are in split structural design at the present stage, the engine rear suspension support is used for connecting the engine and the cushion, the gear selecting and shifting support is used for assembling the gear selecting and shifting flexible shaft of the gearbox, the gear selecting and shifting support is produced by adopting a welding structure, and the size is large. The flexible axle support that shifts is selected to the gearbox fastens through the bolt of borrowing on the gearbox to cover, and the gearbox upper cover is uneven structure, selects the flexible axle support of shifting to erect timing installation face shape and need strictly adjust the cutting according to the shape of gearbox upper cover and dodge, and it is very little to lead to selecting the support of shifting and the gearbox top cap binding face, causes easily to select the fixed unstable problem of support of shifting, generally thickens the support plate for solving this problem, increases the strengthening rib simultaneously and alleviates. Meanwhile, the gear selecting and shifting flexible shaft support is different from a series of gearbox top covers, and the universality is poor because the gear selecting and shifting flexible shaft support must be redesigned according to the top cover.
On the other hand, the joint surfaces between the timing flexible shaft and the gear selecting and shifting flexible shaft support are designed in a plane, after the gear selecting and shifting flexible shaft is fixed with the flexible shaft support, interference exists between the flexible shaft and the flexible shaft support mounting surface, the gear shifting flexible shaft and the gear shifting rocker arm are not parallel, bending is easy to occur, the problem of heavy gear shifting caused by an unnatural state is solved, and the control comfort of the whole vehicle is reduced.
Disclosure of Invention
The utility model provides a suspension support behind multi-functional engine, the structure is light and handy, and processing is simple, simple to operate, and the commonality is high, can solve above-mentioned various interference problems simultaneously.
In order to solve the technical problem, the utility model discloses a technical scheme does: the utility model provides a suspension support behind multi-functional engine which characterized in that: the suspension mounting panel including the integral type structure, suspension cushion backup pad, select to keep off the flexible axle mounting panel, flexible axle installation boss of shifting, be equipped with the suspension connecting hole on the engine suspension installation face of suspension mounting panel, the cushion holding surface of suspension cushion backup pad is personally submitted perpendicular form setting mutually with the engine suspension installation, be equipped with suspension cushion connecting hole on the cushion holding surface of suspension cushion backup pad, the flexible axle installation face of selecting to keep off the flexible axle mounting panel is personally submitted perpendicular form setting mutually with the engine suspension installation, be equipped with the selection on the selection fender flexible axle installation face of selection fender flexible axle mounting panel and keep off the flexible axle fixed orifices, flexible axle installation boss of shifting is located engine suspension installation face, the flexible axle installation face of shifting of flexible axle installation boss is personally submitted the parallel form setting with the engine suspension installation, be equipped with the flexible axle fixed orifices of.
The technical scheme is further limited, and a plurality of reinforcing ribs are arranged between the cushion supporting surface and the engine suspension mounting surface; the reinforcing rib is used for improving the integral strength of the bracket and preventing the bracket from being broken due to bumping of an engine and gear selecting and shifting force.
Compared with the prior art, the utility model, beneficial effect is: the original gear selecting and shifting flexible shaft bracket is eliminated, and meanwhile, in order to prevent interference between the gear shifting flexible shaft and a gear shifting flexible shaft mounting surface, the offset distance of the gear shifting flexible shaft bracket is reduced and is consistent with that of an engine suspension mounting surface; the gear shifting flexible shaft mounting boss is positioned on the engine suspension mounting surface, the height of the boss is determined according to the offset distance of the gear shifting rocker arm, and after the gear shifting flexible shaft is mounted, the gear shifting flexible shaft and the gear shifting flexible shaft mounting surface form a certain offset distance, so that the flexible shaft is prevented from being interfered with the engine rear suspension support to cause damage, the gear shifting flexible shaft is ensured to be in a natural straight state, the gear shifting force loss is reduced, and the gear shifting control comfort of the whole vehicle is improved; the utility model discloses can adopt casting process production, the structure is light and handy simple, and low in production cost is convenient, and intensity is reliable, and the commonality is high, can solve the various not enough that exist at present stage simultaneously, is worth promoting.
