Dual Drive Winch

Abstract

The invention discloses a dual-drive winch which is compact and simple in structure and low in cost and provided with a light dual-drive unit. The dual-drive winch comprises the dual-drive unit, a speed reduction device (1) and a winch drum (2). The output end of the dual-drive unit is connected with the speed reduction device (1). The dual-drive unit comprises a motor (3), a hydraulic motor (4), a speed increasing gear mechanism and a clutch. The output end of the motor (3) is provided with a first gear (5), the output end of the hydraulic motor (4) is provided with a second gear (6), and the input end of the speed increasing gear mechanism is connected with the second gear (6). A clutch gear mechanism of the clutch is arranged between the output end of the speed increasing gear mechanism and the first gear (5). By means of operation of the clutch, a clutch gear of the clutch gear mechanism is connected with the first gear (5) or the output end of the speed increasing gear mechanism, and the output end of the clutch serves as the output end of the dual-drive unit.

Description

Technical field [0001] The invention relates to the technical field of winches, in particular to a dual-drive winch. Background technique [0002] The winch is mainly used for off-road vehicles, agricultural vehicles, yachts and other special vehicles. It is a self-protection and traction device for vehicles and ships. The winch plays a very important role in situations such as towing operations and rescue operations, including self-rescue in the field. [0003] In order to overcome the problems of single-drive winches, such as poor continuous working ability and the need to configure large motors under heavy loads, resulting in higher costs and large volumes, the applicant has designed a winch with two motors, and has obtained Chinese patent, authorized announcement number CN 201990412 U, because the structure also includes a second motor, the output of the second motor is connected to the input of the deceleration device, so that when one of the motors is overheated, the other c...

Problems solved by technology

[0003] In order to overcome the existing problems of the single-drive winch, such as poor continuous working ability, large motor needs to be configured under heavy load, resulting in high cost and large volume, etc., the applicant has designed a winch with two motors, which has been obtained Chinese patent, the authorized announcement number is CN 201990412 U, because the structure also includes a second motor, the output end of the second motor is connected to the input end of the reduction gear, so that when one of the motors overheats, the other motor can participate in the work , and the overheated motor stops working and dissipates heat. When it is necessary to drive a large load, the two motors can participate in the work at the same time. After the traction capacity of the two motors is superimposed, the large load can be easily driven. It has the advantages of dual drive, but when encountering a large load, the two motors configured still require a large structure, and two clutch structures are required for power transmission, so the overall structure cannot be made more compact and simple , the cost is also high, and as part of the motor side of the dual drive unit
