Abstract
The utility model discloses a novel follow-up bearing suspension system used in a duty car, which includes a middle drive bridge; the middle drive bridge is connected with a thrusting rod; the other end of the thrusting rod is connected with a follow-up back bridge; and a balancing bridge suspension device is arranged between the middle drive bridge and the follow-up back bridge. The novel follow-up bearing suspension system used in a duty car solves the problem that the bearing force of the back bridge of a common 4*2 duty car is insufficient; the balancing bridge suspension device is applied on the original back bridge; a follow-up bearing bridge is additionally arranged at the back surface to lead the bearing force of the back bridge of the hollow car to be enhanced, thus meeting the demands of a user and avoiding the tire abrasion of the back bridge; compared with the 6*4 cars, the back bridge is mainly moved to the back; a middle transfixion bridge and a middle transmission shaft are eliminated; the follow-up back bridge is increased; the cost of the whole car is reduced; and the oil consumption is reduced.
Description
Technical field
The utility model belongs to the vehicle bogey, is specifically related to a kind of single load-carrying vehicle that drives double bracing and carries suspension with novel servo-actuated.
Background technology
Existing common 4*2 goods carrying vehicle generally all is that propons turns to, rear-axle drive, and this load-carrying vehicle charge material amount concentrates on the postmedian of car load, the load of back axle is required high, and when adopting single back axle, car load rear portion fulcrum is few, and whole bearing capability is low.And employing duplex bridge, load-carrying capacity improves, but its structure and transmission more complicated, it is that the torque that driving engine spreads out of is delivered to jackshaft through change speed gear box, transmission shaft, by driving gear set in the jackshaft and jackshaft thru shaft torque is passed to transmission shaft between jackshaft tire, bridge respectively; The back axle gear cluster is delivered to the back axle tire with the torque of transmission shaft between bridge; In, the operation of the rotating drive car load of back axle tire.Drive mechanism more complicated like this, the corresponding increase of integral vehicle cost.
Summary of the invention
The purpose of this utility model is that the load-carrying vehicle that provides a kind of drive mechanism simply to have multi-point support carries suspension with novel servo-actuated, to address the above problem.
The technical solution of the utility model is: load-carrying vehicle carries suspension with novel servo-actuated, and it comprises the driving jackshaft, drives jackshaft and connects propelling rod, and the other end of propelling rod connects the servo-actuated back axle, drives between jackshaft and the servo-actuated back axle and establishes the balance bridge draft hitch.
The utility model servo-actuated carrying suspension type of drive is: the torque that driving engine spreads out of is delivered to drive axle through change speed gear box, transmission shaft, by the driving gear set in the drive axle torque is passed to the drive axle tire respectively; The rotating drive car load operation of drive axle tire, the follow-up bridge tire is driven rotation.Its jackshaft drives, rear axle following drives than duplex bridge and reduces transmission shaft between a bridge, reduced integral vehicle cost, solve the problem of bridge bearing ability deficiency behind the common 4*2 goods carrying vehicle simultaneously, on former back axle, use the suspension system of balance bridge, installing a servo-actuated carrying vehicle bridge additional in the back, bridge bearing ability is strengthened after making car load, meets consumers' demand, and avoids the back axle wear on tyres.。Compare the 6*4 vehicle mainly with the back axle reach, connect bridge and tween drive spindle in the middle of the cancellation, increase the servo-actuated back axle, integral vehicle cost reduces, and oil consumption reduces.

Fig. 1 load-carrying vehicle carries the suspension structure scheme drawing with novel servo-actuated.
Fig. 2 load-carrying vehicle carries the suspension schematic top plan view with novel servo-actuated.
Fig. 3 load-carrying vehicle carries suspension transmission scheme drawing with novel servo-actuated.
The specific embodiment
As shown in Figure 1, 2, the structure that drives jackshaft 1 is identical with the back bridge construction of the single rear-axle drive of transmission, and its structure is this tired stating no longer.Drive jackshaft 1 and connect propelling rod 2, the other end of propelling rod 2 connects servo-actuated back axle 3.The structure of servo-actuated back axle 3 is identical with the structure of existing servo-actuated carrying bridge, and its structure is this tired stating no longer.Propelling rod 2 comprises upper thrust rod 4 and lower thrust rod 5, connects balance bridge 6 between upper thrust rod 4 and the lower thrust rod 5, drives to connect steel spring 7 between jackshaft 1, servo-actuated back axle 3 and the upper thrust rod 4.
As shown in Figure 3, the torque that driving engine 8 spreads out of is delivered to through change speed gear box 9, transmission shaft 10 and drives jackshaft 1, by the driving gear set in the drive axle torque is passed to the drive axle tire respectively; The rotating drive car load operation of drive axle tire, servo-actuated back axle 3 tires are driven rotation
After sending out orchid between the bridge of driving jackshaft 1 cancellation duplex bridge, be the thru shaft cancellation of sending out blue transmission torque between bridge, axle housing inner teeth wheels reduce relatively, and the axle housing structure is compact more, and profile reduces relatively.
The transmission gear at servo-actuated back axle cancellation axle housing middle part, axle housing is directly selected rectangular tube for use, and is simple for structure, with low cost; And duplex bridge rear axle case is a cast structure, has designed the gear cluster that transmits torque for the back axle tire in the bridge bag of middle part simultaneously, and complex structure is with high costs.
Claims (2)
1. a load-carrying vehicle carries suspension with novel servo-actuated, and it comprises the driving jackshaft, it is characterized in that driving jackshaft and connects propelling rod, and the other end of propelling rod connects the servo-actuated back axle, drives between jackshaft and the servo-actuated back axle and establishes the balance bridge draft hitch.
2. load-carrying vehicle carries suspension with novel servo-actuated according to claim 1, it is characterized in that propelling rod comprises upper thrust rod and lower thrust rod, connect balance bridge between upper thrust rod and the lower thrust rod, connect steel spring between driving jackshaft, servo-actuated back axle and the upper thrust rod.
