Description
Technical field
The utility model relates to a kind of vehicle component, particularly, and the medium and heavy vehicle that relates to a kind of change speed gear box auxiliary support apparatus and have this change speed gear box auxiliary support apparatus.
Background technology
As shown in Figure 2, the dynamic assembly of medium and heavy vehicle all comprises bonded assembly change speed gear box 7, clutch bell 8 and driving engine 9 successively usually, and the quality of each parts is all bigger, thereby needs the mounting vehicle dynamic assembly suspension to support.During common vehicle engine assembly suspends, suspend before it and generally be installed in front of the engine, after suspend and generally be positioned at clutch bell or engine cylinder-body aft end face position, the support that below change speed gear box, installs additional again that also has suspends.Mostly be to play a supportive role in these suspending apparatus, can carry downward pressure, well prevent vehicle engine assembly skew straight down.But; When vehicle through the road surface of jolting; The change speed gear box that is in the vehicle engine assembly afterbody might produce frequent bob, under the bigger situation of the amplitude of beating, causes the loosening problem of the mounting structure of change speed gear box and the structure of change speed gear box supplemental support etc. easily; Thereby influence the integral vibration damping performance of vehicle engine assembly, cause the damage of mounting structure even change speed gear box etc.And because of design demand, clutch bell thickness has certain restriction, and is as shown in Figure 2, and change speed gear box pitching by a relatively large margin very easily causes the clutch bell of captiveing joint with change speed gear box to bear bigger moment of flexure, thereby cause cracking.Therefore be necessary the bob amplitude of change speed gear box is limited.
For example, number be in the Chinese patent of CN201116078Y at Granted publication, a kind of change speed gear box auxiliary support apparatus of above change-speed box, installing has been proposed.As shown in Figure 1, support 3 is fixedly mounted on the top end face of change speed gear box 7, and the top of support 3 is fastenedly connected on the steel spring 2 through nut, captives joint with two carriages 1 respectively in steel spring 2 two ends, and carriage 1 is fixedly mounted on the vehicle frame.Because various junctions are captive joint rigidly in the change speed gear box auxiliary support apparatus; Thereby jolt amplitude when big when vehicle; Require just very high to the intensity of steel spring 2 and the Joint strenght of each fixed connection place; When the buffer setting of the intensity of steel spring 2, self elasticity or each junction all is not enough to limit upwards beating of change speed gear box, will cause in the change speed gear box auxiliary support apparatus various fixed connection places such as bolted loosening or damage.In addition, when vehicle engine assembly adopts a plurality of mounting structure since each suspend with vehicle frame or vehicle engine assembly between captive joint, thereby a plurality of fixed connection point is easy to generate structural mutual interference or produces stress.
In addition; Vehicle engine assembly is installed on the horizontally disposed vehicle frame, after the installation, chassis side rail 10 vertically on; Usually has certain mounting inclination angle between the spindle axis of vehicle engine assembly and the chassis side rail 10, angle a promptly as shown in Figure 2 (being generally 2.83 ° or 3.5 °).Since driving engine, clutch bell and change speed gear box in the vehicle engine assembly be with bolt be rigidly connected form as a whole; Also has identical mounting inclination angle a between change speed gear box and the chassis side rail 10 like this; Thereby cause in the change speed gear box auxiliary support apparatus; Be connected not tight between the top end face of change speed gear box and the bottom surface of support; Under the situation of jolting repeatedly, make connection loosing easily, cause other the similar junction in the change speed gear box supplemental support also loosening, make the change speed gear box supplemental support not have due effect.
