Abstract
The utility model discloses a kind of electric circulation ball steering gear with double waterproof constructions, comprise a circulating ball assembly and a motor assembly, described motor assembly connects screw rod by four and is connected with described circulating ball assembly, described motor assembly comprises a motor, one protecgulum and a bonnet, the inside of described motor assembly is provided with a sensor housing, the end face of described bonnet is provided with the first fluid sealant ring recess of an annular, the outer wall of described sensor housing is provided with the second fluid sealant ring recess of an annular, it is respectively equipped with a separable O-ring seal in the first described fluid sealant ring recess and the second fluid sealant ring recess.Owing to using the first fluid sealant ring recess and the double sealing structure of the second fluid sealant ring recess, substantially increase the water resistance of motor assembly, it is to avoid the sensor on sensor housing lost efficacy because of moist, was effectively increased the reliability of electric circulation ball steering gear.
Description
Technical Field
The utility model relates to an automobile steering device, more exactly, is an electronic circulation ball steering gear of two waterproof constructions in area.
Background
The recirculating ball steering gear is common automobile steering equipment, and realizes relative rotation through a steel ball arranged between a steering screw rod and a steering nut, so that a sector gear on a steering arm is driven to rotate, and steering is realized. For an electric circulating ball steering gear, electric power assistance is adopted, and steering is more convenient. Because the electric assembly and the circulating ball assembly generally adopt a split structure, the joint is easily corroded by the external environment, so that a sensor in the electric assembly is failed, and the reliability of the steering gear is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that prior art exists to an electronic recirculating ball steering gear of two waterproof constructions in area is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides an electronic recirculating ball steering gear of two waterproof constructions in area, a serial communication port, the electronic recirculating ball steering gear of two waterproof constructions in area contain a recirculating ball assembly and a motor assembly, motor assembly through four connecting screw with the recirculating ball assembly be connected, motor assembly contain a motor, a protecgulum and a back lid, motor assembly's inside be equipped with a sensor housing, the terminal surface of back lid on be equipped with an annular first sealed rubber ring groove, the outer wall of sensor housing on be equipped with an annular second sealed rubber ring groove, first sealed rubber ring groove and second sealed rubber ring inslot be equipped with a separable sealed rubber ring respectively.
The utility model discloses an electric circulating ball steering gear of two waterproof constructions in area has following advantage: during the use, owing to adopt the double seal structure in first sealed rubber ring groove and second sealed rubber ring groove, improved motor assembly's waterproof performance greatly, avoid the sensor on the sensor casing to become invalid because of the humidity, effectively improved the reliability of electronic recirculating ball steering gear. The electric circulating ball steering gear with the double-waterproof structure is simple in structure, obvious in effect, low in cost and high in practicability.
