Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] like Figure 1 ~ Figure 4 As shown, the handle mechanism 1 of the present invention includes a joystick 11, a handle bar 12, a turret 13, a turret seat 14, and a T-shaped shaft 15. The handle bar 12 is fixedly connected to the bottom of the joystick handle 11, and the lower end of the handle bar 12 is welded or The thread is fixedly connected with the top of the turret 13, and the two ends 152 of the T-shaped shaft 15 are respectively supported in the turret side plate 131, and are movably connected with the turret side plate 131, so that the turret 13 can be wound around the two ends of the T-shaped shaft 15. 152 rotates back and forth; the front end of T-shape shaft 15 is supported on the turret seat 14 by bearing 141, makes turret 13 can rotate left and right around the central axis 151 of T-shape shaft 15.

[0024] The present invention also includes an uppe...

Abstract

The invention discloses a travelling control device used for a skidding-steering loader, comprising a handle mechanism, an upper connection rod mechanism, a swing rod mechanism and a lower connection rod mechanism. The upper end of the upper connection rod mechanism is movably connected with the handle mechanism and the lower end thereof is movably connected with one end of the swing rod mechanism; the other end of the swing rod mechanism is movably connected with one end of the lower connection rod mechanism; and the other end of the lower connection rod mechanism is movably connected with atilting inclined plate of a servo plunger pump. The invention adopts the single-rod operation to replace the double-rod operation so as to lead the operation to be convenient and comfortable and meetthe requirements of the ergonomics. The travelling control device is completely independent from other systems of the integral loader and then the mounting and demounting are easy; and the replacing is simple, the maintenance is convenient and the reliability is high. The skidding-steering loader adopting the walking control device of the invention can complete the actions of going forward and backward and turning right and left in a narrow space.

Description

technical field [0001] The invention relates to a walking control device of a loader, in particular to a mechanical control device which is applied to a skid steer loader and can control the walking of the whole vehicle with one hand, and belongs to the technical field of engineering machinery. Background technique [0002] At present, domestically manufactured skid steer loaders are in the stage of gradual development and maturity. The drive mode of the skid steer loader is fully hydraulic drive. The rotation of the wheels is driven by the hydraulic motor to drive the transmission sprocket, and then transmitted to the wheels through the chain. The main features of this kind of machine are small size, compact structure, and limited internal installation space. At the same time, it is required that the skid steer loader can be turned in a small space and can be equipped with various loader attachments. The loader's There are many control points, but its maximum driving speed ...
