Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0016] Such as figure 1 and figure 2 As shown, the positive and negative dual-purpose steering limiting device of the electric pallet truck includes two installation arms 1 for fixed connection with the vehicle frame. Connected with a mounting plate 2, a steering sleeve 3 is welded and fixed on the mounting plate 2, and a steering column 4 is installed through the steering sleeve 3 to rotate, and the steering sleeve 3...

Abstract

The invention discloses a positive and negative dual-purpose steering limiting device for an electric transport vehicle, which comprises two installation arms fixedly connected with the vehicle frame, the two installation arms are arranged parallel to and extending forward, and the front ends of the two installation arms are fixed A mounting plate is connected, a steering sleeve is welded and fixed on the mounting plate, a steering column is installed through the steering sleeve, the upper end of the steering column is connected with a handlebar, and a steering wheel device is installed at the lower end of the steering column. A steering damping device is provided between the steering column and the steering sleeve; the handlebar, steering column and steering sleeve are simple in structure, and a steering wheel device is specially provided on the front side of the car body, and the steering column can rotate 360° in the steering sleeve, The steering is flexible, and the structure of the front end of the car body is small, which helps to reduce the steering space to the greatest extent, and is more suitable for use in greenhouses. The steering damping device set can perform damping restrictions when the steering angle reaches 180°. Here The steering force needs to be increased to play the role of corner reminder.

Description

technical field [0001] The invention relates to the technical field of electric pallet trucks, in particular to a forward and reverse steering limiting device for electric pallet trucks that is easy to operate and use in a greenhouse. Background technique [0002] With the development of greenhouse planting technology, the output of fruits and vegetables grown in greenhouses is getting higher and higher. In order to facilitate the transportation of fruits and vegetables or manage plants in greenhouses, and reduce the labor burden of growers, electric vehicles will be used for short-distance transportation. But the electric vehicles used in the greenhouse are electric vehicles of common structure at present, and the structure is heavy and complicated. Some electric vehicle handlebars can realize 360 ​​° of rotation, and the rotation angle is large, and the rotation is too flexible and inconvenient to use. Contents of the invention [0003] The technical problem to be solved...
