Abstract
The invention provides a rubber spring balance suspension for a transport vehicle. The balance suspension comprises a balance beam support seat, wherein a front rubber spring and a back rubber spring are connected with the balance beam support seat in a hinging way, the balance beam support seat is connected with a balance beam in a hinging way, the lower end of a main vehicle frame is connected with an auxiliary rubber spring, and the auxiliary rubber spring is connected with the balance beam support seat. The rubber spring balance suspension for the transport vehicle has the advantage that the damage caused by the excessive deformation of the front rubber spring and the back rubber spring due to the rotation of the balance beam is avoided.
Description
Technical field
The present invention relates to a kind of transport vehicle rubber spring balance suspension, belong to field of mechanical technique.
Background technology
Domestic existing rubber spring balance suspension by balance suspension bearing, front rubber spring, rear rubber spring, auxiliary rubber spring, equalizing bar, shock absorber, Panhard rod, longitudinal stability bar, etc. parts form.System is connected with vehicle frame by bolt, and equalizing bar and rubber spring are bolted, equalizing bar with in, rear vehicle bridge is connected, Panhard rod, the longitudinal stability bar of guiding and intermal force couple together axis, rear axle and main car frame.The environment on all road surfaces by wheel to axletree to equalizing bar rigid of transmission to rubber spring, the rotation of equalizing bar and torsion make rubber spring be subject to excessive stretching and shearing force, cause rubber spring early damage.
Summary of the invention
The invention provides a kind of transport vehicle rubber spring balance suspension, by changing the connection mode of equalizing bar and front rubber spring and rear rubber spring, between equalizing bar and forward and backward rubber spring, increase the transition of an equalizing bar bearing, forward and backward rubber spring is connected with bolt with equalizing bar bearing, and equalizing bar is connected with sliding sleeve by bearing pin with equalizing bar bearing and can relatively rotates.Thereby the rotation of avoiding equalizing bar causes the excessive deformation of forward and backward rubber spring and causes damage.
For solving above technical matters, the invention provides following technical scheme: a kind of transport vehicle rubber spring balance suspension, described balance overarm comprises main car frame, lateral rod, longitudinal rod, front rubber spring, rear rubber spring, auxiliary rubber spring, strut mount, bumper and equalizing bar, lateral rod is articulated with main car frame, longitudinal rod is articulated with lateral rod, between two longitudinal rods, connects equalizing bar; Main car frame lower end connects strut mount, and front rubber spring and rear rubber spring are all connected on two strut mounts; Bumper is connected on strut mount, and two bumpers are connected on equalizing bar; Described balance suspension also comprises equalizing bar bearing, and described front rubber spring is connected equalizing bar bearing with rear rubber spring, and equalizing bar bearing connects equalizing bar, and connection mode is hinged; Main car frame lower end connects auxiliary rubber spring, and auxiliary rubber spring connects equalizing bar bearing.
Further, there is bearing pin at described equalizing bar bearing middle part, and bearing pin is provided with sliding sleeve outward, and equalizing bar has pin shaft hole, and bearing pin connects sliding sleeve outward, and pin shaft hole connects sliding sleeve.
Further, described front rubber spring is that bolt is connected with the connection mode of equalizing bar bearing.
Further, described rear rubber spring is that bolt is connected with the connection mode of equalizing bar bearing.
This cab-behind-engine vehicle brake operating mechanism the present invention relates to, when the situation of road and complete vehicle quality by wheel and in, back axle passes to the power of equalizing bar, equalizing bar can rotate in balance by bearing pin and sliding sleeve, rear axle stressed, the rotation of equalizing bar is to take relatively rotating that equalizing bar pins axis hole is axle center, and the power that this rotation is delivered on rubber spring is relatively little.Therefore forward and backward rubber spring mainly bears the vertical pressure that comes from main car frame, simplifies the situation that rubber spring is stressed and be out of shape, and reaches and gives full play to the equilibrium activity of balance suspension and the service life of improving rubber spring and whole suspension system.
Accompanying drawing explanation
Fig. 1 is rubber spring balance suspension front elevation for a kind of transport vehicle of the present invention.
Fig. 2 is rubber spring balance suspension lateral plan for a kind of transport vehicle of the present invention.
In the accompanying drawings, 1. longitudinal rod, 2. equalizing bar, 3. bumper, 4. front rubber spring, 5. equalizing bar bearing, 6. auxiliary rubber spring, 7. balance suspension bearing, 8. rear rubber spring, 9. main car frame, 10. bearing pin, 11. sliding sleeves, 12. bearing pins, 13. lateral rods.
The specific embodiment
As depicted in figs. 1 and 2, balance suspension comprises equalizing bar bearing 5, and described front rubber spring 4 is connected equalizing bar bearing 5 with rear rubber spring 8, and equalizing bar bearing 5 connects equalizing bar 2, and connection mode is hinged; Main car frame lower end connects auxiliary rubber spring 6, and auxiliary rubber spring 6 connects equalizing bar bearing 5.
There is bearing pin 10 at equalizing bar bearing 5 middle parts, and bearing pin 10 is outer is provided with sliding sleeve 11, and equalizing bar 2 has pin shaft hole, by pin shaft hole, hangs over outside sliding sleeve 11.
The top side in middle part of equalizing bar 2 has a pin shaft hole, has sliding sleeve 11 in pin shaft hole, is connected with equalizing bar bearing 5, sliding sleeve 11, bearing pin 10, and equalizing bar 2 can relatively rotate with bearing pin 10 centers with equalizing bar bearing 5.The top of equalizing bar bearing 5 is connected with front rubber spring 4, rear rubber spring 8 use bolts respectively, and front rubber spring 4, rear rubber spring 8 are connected with balance suspension bearing 7 use bolts above again.Auxiliary rubber spring 6 is connected with balance suspension bearing 7 use bolts.Balance suspension bearing 7 connects with bolt below main car frame 9.The power passing over by wheel and axis, rear axle when road, cause equalizing bar 2 when bearing pin 10 rotates, the rotation of its equalizing bar can not be directly delivered on front rubber spring 4, rear rubber spring 8, but allow equalizing bar 2 inner sliding sleeves 11 relatively rotate with bearing pin 10, avoid front rubber spring 4, rear rubber spring 8 to be subject to excessive distortion and earlier period damage.
This transport vehicle rubber spring balance suspension the present invention relates to, simple in structure, handle reliably, reduce costs.
The specific embodiment of the present invention does not form the restriction to the application's scope; every within the spirit and principle of the present invention design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection scope of the present invention.
