Problems solved by technology

However, increasing the amount of glass fiber used may cause the problem that the mating members, ie the first rotating member 104 and / or the second rotating member 105, may corrode because the resulting linings 102, 102 may be soaked in water.

Embodiment 1

[0055] exist figure 1 A cross-sectional view showing a device for absorbing torque fluctuations is shown in . The device uses the torque limiter of Example 1 of the present invention. Furthermore, the device is used in a hybrid vehicle having an on-board engine and electric motor.

[0056] The means for absorbing torque fluctuations is provided between a first rotary shaft 1 and a second rotary shaft 2 coaxially arranged to face each other. The device not only transmits the torque from the first rotating shaft 1 to the second rotating shaft 2, but also suppresses torque fluctuations when they occur. The first rotating shaft 1 is connected with and fixed to the flywheel 10 . Note that the flywheel 10 serves as the claimed first member extending radially outward. The flywheel 10 is formed in a disk shape, and is coaxially fixed on the end surface of the first rotating shaft 1 connected to the output shaft of the engine by mounting bolts 11 , 11 .

Embodiment 2

[0069] A torque limiter for a vehicle according to Embodiment 2 of the present invention includes the same constituent elements as those of the torque limiter according to Embodiment 1 except for the through holes 30 where the first and second linings 3, 3' are provided. , 30' have a shape different from the through-hole shape of the first and second linings 3, 3' in the torque limiter according to Embodiment 1. Therefore, only the distinguishing features will be described hereinafter.

[0070] Such as Figure 4 As shown, the through holes 30 , 30 ′ are formed in a tapered shape whose diameter becomes smaller from the inlet side facing the convex portion 10 f , 41 toward the outlet side facing the friction plate 8 . For example, the through holes 30 , 30 ′ have an inlet-side diameter of φ5 mm equal to the diameter in Embodiment 1, and an outlet-side diameter of φ3 mm. Therefore, when the protrusions 10f, 41 having a diameter of φ5 mm are respectively inserted into the throug...

Embodiment 3

[0072] The torque limiter for a vehicle according to Embodiment 3 of the present invention includes the same constituent elements as those of the torque limiter according to Embodiment 1 except for the through-holes 30 where the first and second linings 3, 3' are provided. , 30' have an inner diameter different from the through hole inner diameters of the first and second linings 3, 3' in the torque limiter according to Embodiment 1, and the protrusions 10f, 41 provided except for the flywheel 10 and the pressure plate 4 have A shape different from the convex shape of the flywheel 10 and the pressure plate 4 in the torque limiter according to Embodiment 1. Therefore, only the distinguishing features will be described hereinafter.

[0073] Such as Figure 5 As shown, the protrusions 10f, 41 are formed in a star shape in cross section. The star shape has a periphery in which the recesses and protrusions are arranged one after the other. For example, the protrusions 10f and 41...

Abstract

A torque limiter for vehicle includes a first member, a friction plate, a second member, an urging member, a first facing, and a second facing. The first member is connected to a first rotary shaft. The friction plate is connected to a second rotary shaft. The second member is retained on the first member. The urging member presses the second member toward the friction plate. The first facing is retained on a surface of the first member that faces the friction plate. The second facing is retained on a surface of the second member that faces the friction plate. At least one of the first member and first facing includes a first positioner, thereby positioning the former and latter coaxially with each other. At least one of the second member and second facing includes a second positioner, thereby positioning the former and latter coaxially with each other.

Description

[0001] Related Application Citations [0002] This application is based on Japanese Patent Application No. 2010-248,919 filed on November 5, 2010, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a torque limiter for a damper of a hybrid drive system. Background technique [0004] A hybrid drive system employs both an engine and an electric motor as drive sources. In such a hybrid drive system having a plurality of drive sources, torque fluctuation is more likely to occur than in a drive system in which only one drive source exists. Therefore, the hybrid drive system employs a torque fluctuation absorber having a function of attenuating torque fluctuation between the engine and the electric motor. [0005] For example, Japanese Patent Laid-Open (KOKAI) Publication No. 9-226,392 discloses a technique of suppressing torque fluctuations generated by an engine and an electric motor by means of a damper includi...
