Abstract
The utility model discloses a front hinged or articulated steering tractor. The tractor comprises a transmission case mounted on a tractor head, a steering gear, a steering arm, a vertical pull rod, a left half shaft, a right half shaft, a left haft shaft housing, a right half shaft housing, a left half shaft casing pipe, a right half shaft casing pipe, a left steering knuckle, a right steering knuckle, a steering knuckle arm mounted on the left steering knuckle and a transverse pull rod; the two ends of the steering arm are connected with the output end of the steering gear and the upper end of the vertical pull rod respectively; the left and the right half shafts are sleeved in the left and the right half shaft housings respectively; the half shaft housings are mounted on the case body of the transmission case; the left and the right half shaft casing pipes are connected with the left and the right wheel assemblies of the tractor head respectively; the left and the right half shafts are formed by connecting an inner half shaft with an outer half shaft through a universal joint respectively; the half shaft casing pipes are mounted on the outer half shafts and connected with the universal joints; the lower end of the vertical pull rod is connected with the steering knuckle arm through a ball-joint pin; and the two ends of the transverse pull rod are connected with the left and the right steering knuckles through ball-joint pins. The tractor has small turning radius, is prevented from being easily turned over when turning around a corner, and has high security performance.
Description
Technical field
The utility model relates to a kind of frame-steered tractor, particularly relates to turning to frame-steered tractor before a kind of.
Background technology:
At present radial type, the formula of bowing trac. adopt turns to (being that trailer turns to) after all being, steering wheel rotation when turning to drives rear-axle steering by deflector, pull bar etc., owing to be captive joint between head and the trailer, so when rear-axle steering, the passive realization of front-wheel (being the head wheel) turns to.Big, the easily overturning of this steering mode turn radius, the safety extreme difference.
Summary of the invention
The purpose of this utility model is to provide that a kind of turn radius is little, high safety before turn to radial type, the formula of bowing is dilatory.
For achieving the above object, the solution that the utility model adopts is: this trac. comprises the transmission gearbox that is installed in head, deflector, steering drop arm, longitudinal tie, a left side, right axle shaft, a left side, a right axle shaft shell and a left side, the right axle shaft sleeve pipe, the two ends of steering drop arm are connected with the mouth of deflector and the upper end of longitudinal tie respectively, axle shaft housing is installed on the casing of transmission gearbox, a left side, the right axle shaft sleeve pipe is connected with the wheel set of head respectively, a left side also is installed in the head in addition, the right steering joint, be installed in track arm and intermediate rod on the left steering joint, a left side, right axle shaft is formed by connecting by universal-joint by inner shaft and outer semiaxis respectively, a left side, right inner shaft is enclosed within a left side respectively, in the right axle shaft shell, axle tube is installed on the outer semiaxis and with steering swivel and is connected, the lower end of longitudinal tie is connected with track arm by the ball-joint pin, and the two ends of intermediate rod are by a ball-joint pin and a left side, the right steering joint connects.
The utility model turns to like this: steering wheel rotation, deflector, steering drop arm drive longitudinal tie and move forward and backward, longitudinal tie drives the left steering joint by track arm again and moves, owing to connect by intermediate rod between the left and right steering swivel, therefore intermediate rod drives the right steering joint and does identical motion, finally by driving left and right front tyre and turn to steering swivel bonded assembly axle tube, outer semiaxis.
The utility model is owing to increased steering hardware at head, and the semiaxis of head is designed to be formed by connecting by universal-joint by inside and outside semiaxis, trailer is no longer installed steering hardware, be about to turn to after original and turn to before having made into, therefore it is little to the utlity model has turn radius, is difficult for advantages such as overturning, high safety during turning.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises transmission gearbox, deflector, steering drop arm, longitudinal tie, a left side, right axle shaft, a left side, right axle shaft shell 3, a left side, right axle shaft sleeve pipe 4, steering swivel 5, track arm 6 and intermediate rod 7, the two ends of steering drop arm are connected with the mouth of deflector and the upper end of longitudinal tie respectively, axle shaft housing 3 is installed on the casing 9 of transmission gearbox, a left side, right axle shaft sleeve pipe 4 respectively with the left side of head, right wheel set connects, in addition, a left side also is installed in the head, right steering joint 5, be installed in track arm 6 and intermediate rod 7 on the left steering joint, a left side, right axle shaft is formed by connecting by universal-joint 8 by inner shaft 1 and outer semiaxis 2 respectively, a left side, right inner shaft 1 is enclosed within a left side respectively, in the right axle shaft shell 3, a left side, right axle shaft sleeve pipe 4 is installed in a left side respectively, be connected on the right outer semiaxis 2 and with separately steering swivel 5, track arm 6 is installed on the left steering joint 5, on the right steering joint track arm is not installed, the lower end of longitudinal tie is connected with track arm 6 by the ball-joint pin, and the two ends of intermediate rod 7 are by a ball-joint pin and a left side, right steering joint 5 connects.
Certainly, track arm 6 also can be installed on the right steering joint 5, equally can make left and right steering swivel 5 do identical motion by intermediate rod 7.
The utility model can be installed brake assembly at head, also can be uneasy, and mainly need brake to decide on head.As brake assembly is installed, then axle tube 4 is connected with brake hubs.
