Abstract
Description
Technical Field
[0001] The utility model relates to the field of self-propelled transport vehicles, and specifically to an articulated frame snowmobile. Background Art
[0002] As is well known, a snowmobile includes a small enclosed body mounted on a four-wheel drive chassis, equipped with large-diameter low-pressure tires, a gearbox, a transmission, a braking system, a control system, fenders, etc. At the same time, an on-vehicle differential steering solution generated by the gearbox differential and two on-vehicle gearboxes, as well as a transport vehicle with combined steering, are adopted. Currently, the equipped braking system is a foreign patent product (Russian Patent No. RU2801955 C1, International Patent Classification (IPC) of the utility model: B60F5 / 00 B62D11 / 10 B62D63 / 02).
[0003] The current snowmobiles are small in size and have weak carrying capacity. Moreover, it is a fixed design that combines the braking system and the steering system. This design requires the driver to master specific operating skills, and will increase the loads on the engine, gearbox and braking system, increase fuel consumption, and is not conducive to energy conservation and environmental protection.
[0004] In addition, a snowmobile named "SHERP" is disclosed on the website https: / / sherp.ru / sherp_n. The carriage is mounted on a four-wheel drive chassis and is equipped with ultra-low pressure vacuum tires and a specific on-vehicle turning system. This snowmobile is provided with a combined control system for the movement trajectory and braking, and also requires specific control skills. This design not only increases the loads on the engine, gearbox and braking system, but also increases fuel consumption, and is equally not conducive to energy conservation and environmental protection.
[0005] Later, engineers used a rotary and coupling mechanism solution to connect two frame components. An axle with two wheels is fixedly connected to each frame component, and the vehicle is steered by rotating one frame component relative to the other frame component. This solution is widely used in wheeled tractors and snowmobiles (Russian Patent No.: RU2458801C2, International Patent Classification (IPC) of the utility model: B60G7 / 00; B62D63 / 02; B60G21 / 45, Russian Patent No. 2102250, International Patent Classification (IPC) of the utility model: B62D19 / 00). However, this design still has the following defects: In order to ensure high maneuverability, a large space needs to be left between the front and rear carriages, which reduces the effective space of the carriage and the passenger-cargo compartment.
[0006] In order to eliminate the above defects, improve the controllability and maneuverability of the snowmobile, and at the same time control the effective volume of the vehicle body to remain at the level of a single-frame snowmobile, it is also necessary to reduce fuel costs, improve fuel economy, and achieve the purpose of energy conservation and emission reduction.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] By combining the use of frame folding and skid steering (redistributing torque to the wheels), the mobility of this vehicle in narrow spaces can be improved compared with vehicles driven by relatively rotating a part of the frame.
[0013] Since the front and rear parts of the vehicle body are closely connected by an elastic folding awning, the internal space of the snowmobile has a relatively large independent space.
[0014] Compared with the airborne special plan, the fuel loss during the vehicle operation of this snowmobile is reduced, which has a positive impact on the improvement of fuel efficiency and the reliability of the design. Description of the Drawings
