Abstract
The utility model relates to the technical field of vehicle steering, in particular to a front axle steering system of an electric tractor. The front axle steering system comprises a front axle composed of a front axle longitudinal beam and a front axle transverse beam and steering knuckles connected with the front axle transverse beam. The front axle longitudinal beam is connected with a tractor body, the steering knuckles are connected with wheel hubs, the upper end faces of the steering knuckles extend to the two sides of a main pin hole, the sides, far away from the front axle transverse beam, of the upper end faces of the left steering knuckle and the right steering knuckle are respectively provided with a steering ball, and the two steering balls are connected through a pull rod. The front axle is formed in a punched mode at a time through high-strength steel, the strength is larger, the structure is simpler, and the production efficiency is higher. An original needle bearing is replaced by a conical roller bearing, the bearing capability of the steering knuckles is improved, the steering flexibility is higher, and the service life is longer. The steering balls are installed on steering cleats, the steering ball on the left steering cleat and the steering ball on the right steering cleat are connected through the pull rod, a left wheel and a right wheel are steered synchronously, and the steering radius is reduced.
Description
Technical field
The utility model relates to Vehicular turn technical field, is specifically related to a kind of electrically propelled traction vehicle steering swivel system.
Background technology
The propons of existing electrically propelled traction vehicle steering swivel system is mainly by being welded, and complex structure and heaviness, can only connect single-wheel, can not connect two-wheel.Its slewing journal structure complexity, adopts needle bearing in steering swivel, radial dimension is larger, and while work under high speed, heavy lift condition, service life is short, and vibration and noise are larger, and steering flexibility is poor.Tractor truck left and right wheels turn radius is inconsistent, and turn radius is larger, and stability is also poor.
Utility model content
In order to address the above problem, the utility model provides a kind of electrically propelled traction vehicle steering swivel system, and it has improved steering swivel load-carrying capacity and alerting ability, has reduced turn radius, and structure is simpler.
The technical solution of the utility model is: a kind of electrically propelled traction vehicle front axle steering system, comprise the propons being formed with propons crossbeam by front sleeper and the steering swivel being connected with propons crossbeam, described front sleeper is connected with vehicle body, described steering swivel is connected with wheel nave, extend to kingpin bore both sides the upper surface of described steering swivel, a steering ball is respectively being equipped with away from a side of propons crossbeam in the upper surface of two steering swivels in left and right, between two steering balls, connects by pull bar.
Further, between described front sleeper and propons crossbeam, a snubber block is housed.
Further, in described steering swivel, tapered roller bearing is housed.
The beneficial effects of the utility model are: propons adopts high strength steel one time punching molded, and intensity is larger, and structure is simpler, and production efficiency is higher, and can realize Double-wheel structure.Fill steering ball in left and right turn joint upper surface away from a side of propons crossbeam, and by pull bar, steering ball is coupled together, realized turning to synchronously of left and right wheels, reduced turn radius.Car load adopts rear drive mode, and front-wheel is only implemented divertical motion, by the function centralization of front-wheel, has further reduced turn radius.Change original needle bearing into tapered roller bearing, can bear radial and axial connected load, improved the load-carrying capacity of steering swivel, the higher and longer service life of steering flexibility.Between front sleeper and propons crossbeam, snubber block is set, for tractor truck has increased a cushion effect, makes car more steadily comfortable in the time of operation.
Accompanying drawing explanation
Fig. 1 is the utility model birds-eye view;
Fig. 2 is the utility model transverse sectional view;
Fig. 3 is the utility model snubber block schematic diagram;
Fig. 4 is the utility model slewing journal structure schematic diagram;
Wherein: 1-propons; 2-steering swivel; 3-front sleeper; 4-propons crossbeam; 5-steering ball; 6-pull bar; 7-snubber block; 8-steering yoke bolt; 9-lining; 10-bearing; 11-lubricating cup; 12-steering column jacket.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figs. 1 and 3, propons 1 of the present utility model is formed by connecting with propons crossbeam 4 by orthogonal front sleeper 3, and described front sleeper 3 is connected with vehicle body, and described propons crossbeam 4 couples together by steering swivel 2 and the wheel hub of trailer wheel.Propons 1 is to adopt the one time punching molded integral piece of automobile high-strength steel, and its more traditional tractor truck propons has larger intensity, and structure is simpler, and production efficiency is higher.
Fig. 4 is the structural representation of steering swivel 2, and steering swivel 2 interconnects with steering yoke bolt 8, lining 9, bearing 10, lubricating cup 11, steering column jacket 12 these parts.Steering yoke bolt 8 passes the kingpin bore at steering swivel 2 two ends, and passes through screw lock.In the middle of 10, two bearings of symmetrically arranged two bearings are housed on the steering yoke bolt 8 in steering swivel 2, be provided with a lubricating cup 11, described bearing 10 overcoats have a steering column jacket matching with it 12.A lining 9 is housed respectively between the upper and lower end face of steering column jacket 12 and steering swivel 2, and described lining 9 is step, the end contact of its radial flange and bearing 10, and axial ledge is connected between steering column jacket 12 and the upper and lower end face of steering swivel 2.Described bearing 10 is tapered roller bearing, can bear radial and axial connected load, improves the load-carrying capacity of steering swivel, the higher and longer service life of steering flexibility.
Described steering swivel 2 is erietiform steering swivel, and extend to kingpin bore both sides its upper surface, and a steering ball 5 is respectively equipped with in the upper surface of left and right turn joint 2 in the one end away from front sleeper 3, and 5 of two of left and right steering balls couple together by a pull bar 6.In the time turning to, when left side steering swivel rotates, by the pull bar 6 on steering ball 5, can drive right hand steering joint to rotate, thereby guarantee right wheel and revolver parallel rotation, turn radius is consistent, and reduces the turn radius of the wheel that is positioned at outside, and vice versa.Car load adopts rear drive mode, and front-wheel is only implemented divertical motion, by the function centralization of front-wheel, has further reduced turn radius.
As shown in Figure 2, between the front sleeper 3 of described propons 1 and propons crossbeam 4, be bolted, both are equipped with the snubber block 7 of a quality of rubber materials in junction, the impact when reducing tractor truck and travelling, and protection propons 1, and more steady when tractor truck is travelled.
The above; be only the specific embodiment of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
