Abstract
A silencer for a leaf spring for a commercial vehicle is provided. The silencer includes an upper rubber body having defined therein a fitting hole into which a second leaf spring is press-fitted, with a top surface of the upper rubber body serving as a contact surface in contact with a first leaf spring, and a lower rubber body having defined therein an accommodation space, with a first buffering protrusion being provided on a bottom surface of the lower rubber body such that a third leaf spring is able to be in contact with the first buffering protrusion.
Claims20
A silencer for a leaf spring for a commercial vehicle, the silencer comprising:
- an upper rubber body having defined therein a fitting hole into which a second leaf spring is press-fitted, with a top surface of the upper rubber body serving as a contact surface in contact with a first leaf spring;
- and
- a lower rubber body having defined therein an accommodation space, with a first buffering protrusion being provided on a bottom surface of the lower rubber body such that a third leaf spring is able to be in contact with the first buffering protrusion.
A vehicle comprising:
- a leaf spring assembly comprising a first leaf spring, a second leaf spring, and a third leaf spring;
- and
- a silencer attached to the leaf spring assembly, the silencer comprising:
- an upper rubber body including a fitting hole, wherein the second leaf spring is press-fitted in the fitting hole, and wherein a top surface of the upper rubber body contacts the first leaf spring;
- and
- a lower rubber body including an accommodation space and a first buffering protrusion on a bottom surface of the lower rubber body, wherein the first buffering protrusion is configured to be able to contact the third leaf spring.
A method of performing a multistage buffering operation of a silencer mounted on a leaf spring assembly comprising a first leaf spring, a second leaf spring, and a third leaf spring bonded in a stack, the method comprising:
- during a bumping behavior, performing a first buffering operation comprising bringing a first buffering protrusion provided in a lower rubber body of the silencer into contact with a top surface of the third leaf spring;
- and
- during the bumping behavior, performing a second buffering operation comprising compressing the lower rubber body, reducing a height of a buffering space provided in the lower rubber body, and bringing a second buffering protrusion provided at a bottom surface of the lower rubber body into contact with a top surface of the buffering space.
