Abstract
The utility model relates to the field of agricultural transport vehicles, particularly a rear axle swing link device which is used for transferring longitudinal reactive force of a rear axle of a three-wheel agricultural transport vehicle. The utility model is composed of a swing link 3, and connecting devices which are arranged on the both ends of the swing link 3, and the connecting device is composed of a swing link bracket 5, a pin shaft 8 and a cotter pin 4. The utility model is characterized in that the connecting device arranged on one end of the swing link 3 is provided with a ball pin component which is composed of a ball head seat 6 and a ball head 7, and the ball head 7 is connected with the pin shaft 8, and the ball head seat 6 and the swing link 3 are fixed into integration. Therefore, the utility model avoids the camber wear and torsion breakage of a pin hole arranged on the end of the swing link and solves the problem of torque move interference between the rear axle and a vehicle frame.
Description
The utility model relates to the agriculture truck field, refers in particular to a kind of back axle fork device that is used to transmit the longitudinal force of three-wheeled farm transport vehicle back axle.
At present, general path of motion when respectively establishing a rigidity fork at two ends, the back axle left and right sides and transmitting the longitudinal force of back axle and guarantee that trailing wheel is beated on the three-wheeled farm transport vehicle, one end of fork links to each other with vehicle frame, and the other end links to each other with the back axle central siphon, and two ends are pin type and connect.When three-wheeled farm transport vehicle travels, because the ground-surface that wheel contacted of back axle both sides is uneven or turns to the inclination of vehicle body when travelling, relative twisting motion can appear between back axle and the vehicle frame, but the fork that is between back axle and the vehicle frame is a rigidity, the pin type connection at fork two ends does not allow fork that twisting motion is arranged again, therefore back axle is restricted with relative twisting motion between the vehicle frame, this just causes fork two ends pin-and-hole eccentric wear and torsional fracture to occur easily, has influenced the reliability of service of car load.
The purpose of this utility model provides a kind of three-wheeled farm transport vehicle back axle fork device, can guarantee the freedom of the relative twisting motion between back axle and the vehicle frame, to solve the eccentric wear and the torsional fracture problem of swing link end part pin-and-hole.
The purpose of this utility model is achieved in that
This device comprises the connecting device of fork and rear and front end, connecting device is made up of fork support, bearing pin, spring cotter, it is characterized in that being provided with the ball pin assemblies of being made up of ball cap and bulb in the connecting device of fork one end, wherein bulb is connected with bearing pin, and ball cap and fork are fixed into one.
Detailed structure of the present utility model is provided by drawings and Examples.
Fig. 1 is the connecting device cutaway view of swing link end part and the location diagram of fork and back axle.
Fig. 2 is the mounting structure scheme drawing of the utility model on car load.
Describe concrete structure of the present utility model below with reference to the accompanying drawings in detail:
As depicted in figs. 1 and 2, the utility model comprises fork 3 and the rear and front end connecting device of being made up of fork support 5, bearing pin 8, spring cotter 4, be provided with the ball pin assemblies of forming by ball cap 6 and bulb 7 in the connecting device of front end, ball cap 6 is enclosed within the surface of bulb 7, itself and fork 3 are welded into an integral body, be provided with pin-and-hole in the bulb 7, bearing pin 8 passes from pin-and-hole, and fork 3 and fork support 5 are coupled together.In the connecting device of rear end, fork support 5 links to each other with bearing pin 8, and the support 9 that is connected that stretches out on bearing pin 8 and the back axle 2 links to each other, to realize the transmission of back axle 2 to the power of fork 3.
Its working process is as follows:
When three-wheeled farm transport vehicle travels, the longitudinal force that back axle 2 produces is delivered to bearing pin 8 through connecting support 9, again from the fork support 5 of rear end, fork 3, ball cap 6, bulb 7, bearing pin 8, the fork support 5 of front end is delivered to vehicle frame 10 successively, rear wheel 1 can be along the path of motion that is determined by fork 3 simultaneously, promptly the bearing pin center 11 with fork 3 front ends is the center of circle, wire length with bearing pin center 11 and rear wheel center 12 is the circular arc bob of radius, fork 3 is fixed into one with ball cap 6, can rotate with respect to bulb 7, bulb 7 can rotate with respect to bearing pin 8.When between back axle 2 and the vehicle frame 10 relative twisting motion being arranged, this relative twisting motion just is converted into relatively rotating between bulb 7 and the ball cap 6, can not occur the interference of relative twisting motion between back axle 2 and the vehicle frame 10.
The utility model adopts the compound type connection structure of bearing pin and ball pin assemblies at swing link end part, back axle and relative twisting motion between the vehicle frame were converted into relatively rotating between ball cap on the fork and the bulb when three-wheeled farm transport vehicle was travelled, solve the twisting motion interference problem between back axle and the vehicle frame, avoided the eccentric wear and the torsional fracture of swing link end part pin-and-hole.This apparatus structure compactness can be the directly transformation of the way on the pin type bonded assembly fork device at the two ends of generally adopting at present, and the pin-and-hole force-bearing situation of swing link end part is obviously improved, and reliability of service improves, and trial product is on probation through real vehicle, and effect is very good.
