Description

Technical Field

[0001] The utility model relates to the technical field of throttle valves, in particular to a throttle valve cable assembly structure. Background Art

[0002] The throttle valve is an air intake regulating component of an internal combustion engine. The throttle valve mainly rotates the cable disc through the cable, thereby driving the valve plate to rotate through the cable disc to adjust the opening size of the throttle valve intake passage. In order to ensure the stability of the cable, a cable bracket is generally installed on the throttle valve assembly to support the cable and make it more stable when in use. However, the current cable bracket is generally installed on the throttle valve body. Since the cable bracket needs to occupy a certain space, during the installation process, the cable bracket on the throttle valve body is more likely to interfere with other structures of the vehicle, thereby affecting the installation limitations of the throttle valve assembly in the vehicle.

The center of the cable 202 fixing hole 301 on the cable bracket 3 coincides with the center of the cable fixing groove 103, which ensures the life of the cables 202 and ensures that the throttle valve will not get stuck during acceleration and deceleration during operation.

[0027] There are two cable brackets, and the cable 202 fixing holes 301 on the two cable brackets 3 correspond to the two cables 202 respectively.

[0028] A first limiting structure is provided on the fixing boss 101 , and correspondingly, a second limiting structure matching with the first limiting structure is provided on the cable bracket 3 .
